  *   We can work on it but probably, it is safe to problem list the test for linux for now.

Ok, great.  May I add you as reviewer ?

Best regards, Matthias

This test tests the newly added public API of BasicGraphicsUtils (exposing the functionality provided by internal class SwingUtilities2) for use by third party LAFs in JDK9 and beyond, so I guess we cannot ditch it completely. Regarding the test fragility, I actually incorporated the changes proposed by Phil, which are

- add "x"  to the position it passes to checkImageContainsSymbol

- increase WIDTH

- use rendering hints to use aliased text in testDrawString()

which makes the test pass in linux but it now creates problem in macos. We can work on it but probably, it is safe to problem list the test for linux for now.

It tests something important or else I'd ditch it completely ..

Prasanta  ?

Hi Matthias,

looks good, I definitely second that. Let's wait what 2d folks (Phil?) have to say.

Best regards

Please review the following small change .

It excludes javax/swing/plaf/basic/BasicGraphicsUtils/8132119/bug8132119.java  ; the test  seems to  be  fragile on various Linux distros ,
    for instance on our Ubuntu 18 .

The issues are already described in detail  here :


"All in all this test looks really fragile. It is a miracle it has passed as much as it has .. I think Linux
may expose this because the font being used is more or less "fixed" on the other platforms but
on Linux the font being used varies."

As long as 8229935  is not fixed,  the test should be excluded at  least  on Linux  .

Bug/webrev :



Thanks, Matthias
